Item Acesso aberto (Open Access) Efeito da monocultura da palmeira de dendê (Elaeis guineensis Jacq.) sobre a fauna de primatas na Amazônia Oriental(Universidade Federal do Pará, 2016-04-25) MINEIRO, Ivo Gabriel Barros; OLIVEIRA, Ana Cristina Mendes de; http://lattes.cnpq.br/1199691414821581Item Acesso aberto (Open Access) Efeito do plantio de dendê (Elaeis guineensis Jacquin 1763) sobre a diversidade funcional de mamíferos terrestres(Universidade Federal do Pará, 2014-03-12) MAUÉS, Paula Cristina Rodrigues de Almeida; OLIVEIRA, Ana Cristina Mendes de; http://lattes.cnpq.br/1199691414821581We studied the effect of palm tree planting on the functional diversity of terrestrial mammals in a region of the Amazon Forest in the northeast of the State of Pará, Brazil. We evaluated through measures of Functional Diversity (FD) the impacts that this planting can have on the functional groups of medium and large terrestrial mammals. In addition to the species richness we consider the abundance of species in the analyzes involving the functionality, through the Biological Trait Analysis (BTA) and the Functional Diversity Analysis based on the Rao quadratic entropy index (FDq). No effect of palm oil planting on the FD of the mammals was observed, considering only the species richness. However, in the analyzes in which the abundance of the species was considered (FDq and BTA), it was possible to observe the effects on the functional groups. The functional traits most affected by the effect were: general food habits, bunodon dentition, diurnal activity period, diet based on fruits, seeds, invertebrates and exudates, social behavior in small groups, arboreal locomotion, sub-forest forest strata and sub-canopy and the functional groups most affected by palm planting were primates and other arboreal species, compromising the functions of seed predation and dispersion, decreased nutrient cycling, reduced invertebrate control, decreased herbivory, and altered species life history vegetables.Item Acesso aberto (Open Access) Estruturação da comunidade de odonata (insecta) na Amazônia Oriental: efeitos espaciais, ambientais e morfológicos em igarapés íntegros e alterados(Universidade Federal do Pará, 2015-12-04) OLIVEIRA JUNIOR, José Max Barbosa de; JUEN, Leandro; http://lattes.cnpq.br/1369357248133029Item Acesso aberto (Open Access) Influência da exploração madeireira na estrutura do hábitat e diversidade das assembleias de peixes de riachos na amazônia oriental(Universidade Federal do Pará, 2017-02-17) PRUDENTE, Bruno da Silveira; MONTAG, Luciano Fogaça de Assis; http://lattes.cnpq.br/4936237097107099Logging is one of the main activities responsible for the deforestation in the Amazon and is considered an important threat to biodiversity in this region. However, the international market demand for sustainable forest products has resulted in a partial substitution of the conventional exploration method (CE) with the reduced impact exploration (EIR) technique, also considered an important strategy to minimize damages to the Amazon forest and its biodiversity. However, little is known about the effect of these activities on the structure and functioning of riparian ecosystems and their biological communities. In this sense, the present study aimed to evaluate the effect of different methods of logging on the structure of the physical habitat of streams and taxonomic and functional diversity of the fish assemblages of these environments, as well as the elaboration of multimetric indices that allow a rapid and robust evaluation of the ecological integrity of these environments. A total of 47 streams were sampled in the Rio Capim basin, 13 of which were in unexplored areas, 11 in EC areas and 23 in RIL areas. The habitat structure was characterized based on 19 environmental variables, later compared between the different exploration methods. The fish assemblages were sampled using hand net, with a standardized effort, and evaluated as to the composition and different components of the functional diversity. Both methods of logging resulted in changes in the structure of the physical habitat of the streams, however only in areas of CD these changes influenced the taxonomic composition of fish species. In RIL areas only variations in the relative abundance of fish species were observed in relation to the temporal exploitation gradient. Despite the above results, the presence of logging, be it EC or EIR did not affect components of the functional diversity of fish assemblages. However, changes in the habitat of rachis associated with the presence of logging had been directly related to the functional attributes commonly associated with generalist strategies of the species, which are common associated with altered environments. According to the multimetric indexes, streams in RIL areas presented better habitat integrity when compared to streams in CD areas, but still lower than habitat integrity in unexplored streams. On average, EIR areas also presented intermediate values of biotic integrity, however, this differed only in areas of CD. In the studied region, RIL showed to be an interesting strategy to minimize alterations in riach ecosystems resulting from logging. However, the present study was conducted only on a local spatial scale, and considering areas that went through a single exploration cycle. However, changes in physical habitat show that EIR also influence the structure and consequently the ecological integrity of these environments, reinforcing the need for a greater number of studies to understand the real effect of this activity in these environments.Item Acesso aberto (Open Access) Uso da abordagem diversidade funcional na estrutura das comunidades de macroinvertebrados aquáticos(Universidade Federal do Pará, 2016-02-29) ANDRADE, Ana Luiza; MONTAG, Luciano Fogaça de Assis; http://lattes.cnpq.br/4936237097107099; FERREIRA, André Luiz Netto; http://lattes.cnpq.br/1272360228203358Aquatic macroinvertebrates are largely used to evaluate the health and functioning of lotic ecosystems. These organizations operate in maintenance of ecosystem processes and are responsible for nutrient cycling and energy flow. But understand the mechanisms that structure such communities is still a challenge to ecological studies, with that comes the need to study new approaches and metrics investigative In this context it was inserted the functional diversity whose approach is based on morphological, physiological or behavioral characteristics of the species that play a role in the community or ecosystem.. In this sense, we did a literature review to investigate the trends and global gaps of functional diversity of aquatic macroinvertebrates of lotic systems. Studies with this approach are relatively new to the group and showed a rapid growth over the years, but has been little used in neotropical regions. Among the investigated items found variations in basic concepts of functional approach between the articles, which can lead to erroneous interpretations. We also find that the functional responses of aquatic insects were more abundant among the macroinvertebrates and more frequently in studies evaluating the effect of environmental impacts anthropic. At last, we tested the applicability of the functional diversity approach. We evaluated the functional and taxonomic responses of the orders Ephemeroptera, Plecoptera and Trichoptera of streams inserted in areas of oil palm plantations comparing them to streams of forested areas of Eastern Amazon. We found that the abundance of EPT differ among communities, being higher in plantations, while the species richness was greater in the forest, with the loss of nine genera EPT in oil palm streams. Even with this biological loss, functional diversity did not differ between communities. However, when we analyze the characteristics of the environment, there were differences in pH, number of trunks and proximity to roads, and these, along with water temperature were able to select the attributes functional trophic habit and body size in the EPT community.
